Pop music, short for 'popular music', is a genre that originated in its modern form during the mid-1950s in the United States and the United Kingdom. It is characterized by its catchy melodies, simple chords, and a focus on recording, production, and technology rather than live performance. Pop music often draws influences from various other genres, including rock, dance, hip hop, and country. Its primary aim is to appeal to a general audience rather than a particular subculture or ideology. Pop songs are generally short to medium in length, with a repetitive structure that includes verses and a chorus. Artists like Michael Jackson, Madonna, and The Beatles are widely recognized as significant contributors to the genre. Today, pop music continues to evolve, incorporating elements from other musical styles and adapting to new trends.
